China’s 2060 climate pledge is ‘largely consistent’ with 1.5C goal, study finds New research has found that China’s pledge to achieve “carbon neutrality” before 2060 is “largely consistent” with the Paris Agreement’s aim of limiting global warming to 1.5C. But, to stay below this level of warming, the country will need to aim higher than its current net-zero goal and accomplish “deep” emission reductions in the near term, the authors state. According to the study, to hit the 1.5C goal, the world’s largest emitter would need to cut its total carbon dioxide (CO2) emissions and energy consumption by more than 90% and 39%, respectively, by 2050 – compared to a “no-policy” scenario where the government has not and will not impose climate policies. ....
Study Evaluates China’s Measures to Achieve the 1.5°C Warming Limit Written by AZoCleantechApr 23 2021 Almost all nations in the world agreed to take measures to restrict the average increase in worldwide surface temperature to within 2°C, or preferably 1.5°C than preindustrial levels, in accordance with the Paris Agreement. Image Credit: Alexey Rezvykh/shutterstock.com But from the time the Agreement was signed, concerns about global warming propose that nations should aim for the 1.5°C preferable warming limit. For China, what are the consequences of making attempts to achieve this lower limit? Professor Hongbo Duan from the University of Chinese Academy of Sciences and Professor Shouyang Wang from the Academy of Mathematics and Systems Science of the Chinese Academy of Sciences and their colleagues have tried to find a solution to this question. ....
E-Mail A new multi-model analysis suggests that China will need to reduce its carbon emissions by over 90% and its energy consumption by almost 40%, in order to meet the more ambitious target set by the 2016 Paris Agreement. The Agreement called for no more than a 1.5°Celsius (C) global temperature rise by 2050. These results provide a clear directive for China to deploy multiple strategies at once for long-term emission mitigation, the authors say. The findings also highlight the need for more research on the economic consequences of working toward a 1.5°C warming limit, arguing that current studies are far from adequate to inform the sixth assessment report (AR 6) on climate change planned for release by the United Nations Intergovernmental Panel on Climate Change in 2022. Most research to inform climate policy has centered on the goal of 2.0°C, and to date, there is clearly no consensus on the attractiveness of a 1.5°C target, particularly given the uncertainty in a ....
Kevin Frayer/Getty Images China will have to clean up its entire power sector by 2050 if the world is to achieve the Paris Agreement goal of holding global warming to 1.5°C, meaning its carbon emissions must peak much earlier than currently planned. The country, which is the planet’s biggest emitter, made a surprise pledge last year to reach “carbon neutrality” by 2060, leading to a fresh wave of research on how it can end its huge reliance on coal and green its fast-growing economy. Advertisement An analysis published today adds to the growing consensus that China’s electricity sector must be fully decarbonised by 2050. At the start of last year, coal provided around two-thirds of electricity supplies in the country, with renewables, including hydro, at around a quarter. ....
